Jurassic Explorers

Somehow this ended to be a budget deck, which acutally wasn't the intention to begin with, but ok.

As seen from the decklist it combos on Evelina, Valley Searcher with the other Explorers, to push the Dinosaurs into extreme values. Using Dark Return to bring back Explorers and Excavate on the Dinosaurs, preferably a Pteriax Hachling to trigger its Echo.

I use Devour to forcekill several of my units to either bring the back for applying Evelina again or to kill a strong Pteriax (maybe even with Killer) and excavate it again.

It works quite well in ranked, scoring 6 wins in 8 matches so far.

Any ideas on enhancing are appreciated.
